EXPERIMENTAL STUDY ON SMOKE FLOW, COMBUSTION PROCESS AND SUBAREA MODEL FOR THE FIRE IN A LONG NARROW CONFINED SPACE

摘要

Presently no study on the fire in an underground fuel depot has been reported. In this paper, the combustion process, the smoke flow and subarea model about the fire in a long narrow confined space are investigated by experiment and analysis. Through experiment and mechanism analysis, the fire zones are divided into flame zone, high temperature thermal plumes zone, fresh air supplement zone transitional zone and "dead zone". The experimental data of the temperature and the concentration for HC, CO, CO_2,O_2 are presented for different zones in the paper, too.
